What executable programs have names that are just one character long, and what do they do??

1 answer:

5 0

Any program can be an executable, and it can be named anything the user chooses, and would still function exactly the same.

PC games are often run via an executable. If you rename that executable to something else, it will still function perfectly fine.

Therefore, one character long executable programs are just executable programs that have been renamed one character long, and will function as intended.

Display all the natural numbers from 1 to 100 that are exactly divisible by 3 and 7 using FOR … NEXT. Without using Mod

Tcecarenko [31]

Answer:

FOR i% = 1 TO 100

IF ((i%\3) = i%/3) AND ((i%\7) = i%/7) THEN

PRINT i%

END IF

NEXT i%

Explanation:

Of course using MOD would be cleaner, but another way to check if a number is integer divisable is to compare the outcome of an integer division to the outcome of a floating-point division. If they are equal, the division is an integer division.

Make sure to read all of these specifications carefully. Write a function, named array_shifter, that accepts an array of doubles

rosijanka [135]

Answer:

import java.util.Arrays;

public class num2 {

public static void main(String[] args) {

//Create and initialize the first array

double [ ]arr = {3.5, 5.6, 4.5, 6.7};

// Get the length of the array

int n = arr.length;

//Call the method Array Shifter inside the output statement

System.out.println(Arrays.toString(array_shifter(arr,n)));

}

static double [] array_shifter(double [ ] doubleArray, int n){

double [] narr = new double[n+1];

//Loop through from index 1

for(int i =0; i<narr.length-1; i++){

narr[i] = doubleArray[i];

}

//Put a new element at the last index

narr[narr.length-1] = 1.1;

return narr;

}

Explanation:

This is implemented in Java

The method array_shifter creates a new array that is one element larger than the array it received as argument and returns it

A program is required to three (3) numbers. calculate and print their total

podryga [215]

A program that is required to three (3) numbers. calculate and print their total is given below:

<h3>The Program</h3>

import java.util.Scanner;

public class SumAndAverage {

public static void main(String[ ] args) {

System.out.println("Enter three numbers - ");

// Accepting and finding sum of numbers.

int sum = 0;

Scanner sc = new Scanner(System.in);

for (int i = 0; i < 3; i++)

sum += sc.nextInt( );

// Printing sum and average.

System.out.println("Sum - " + sum);

System.out.println("Average - " + (sum / 3f));

}

The output would request three different numbers, then add them up, and display the output of the sum and then display or print their total

Nuetrik [128]

Object-oriented databases is more flexible and stores data as well as instructions to manipulate the data.

A system known as an object database uses object-oriented programming to represent data in the form of objects. Different from relational databases, which are table-oriented, are object-oriented databases.

The concept of object-oriented programming languages, which is currently popular, is the foundation of the object-oriented data model. Overloading, polymorphism, and inheritance Object-oriented programming fundamentals that have found use in data modelling include object-identity, encapsulation, and information hiding with methods to provide an interface to objects. The rich type system, which includes collection and structured types, is supported by the object-oriented data model as well.

In contrast to relational databases, which can only handle one type of data, object databases can handle multiple data types. Unlike conventional databases like hierarchical, network, or relational, object-oriented databases can handle a variety of data types, including text, numbers, images, voice, and video.

Also, Reusable code, realistic modelling, and increased dependability and flexibility are all provided by object-oriented databases.

Given an integer variable count, write a statement that displays the value of count on the screen. Do not display anything else

Irina-Kira [14]

Answer:

cout<<count;

Explanation:

The above statement is in c++ which display the value of count .The cout statement is used in c++ to print the value on console .

Following are the code in c++

#include <iostream> // header file

using namespace std; // namespace

int main() // main method

{

int count=90; // count variable

cout<<count; // display the value of count

return 0;

}

Output:

In this program we have declared a count variable of integer type which is initialized by 90 and finally displays the value of count on the screen.
